2020-08-03udp_tunnel: add the ability to hard-code IANA VXLANJakub Kicinski4-8/+76
mlx5 has the IANA VXLAN port (4789) hard coded by the device, instead of being added dynamically when tunnels are created. To support this add a workaround flag to struct udp_tunnel_nic_info. Skipping updates for the port is fairly trivial, dumping the hard coded port via ethtool requires some code duplication. The port is not a part of any real table, we dump it in a special table which has no tunnel types supported and only one entry. This is the last known workaround / hack needed to convert all drivers to the new infra. Signed-off-by: Jakub Kicinski <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>

2020-08-03net/mlx5e: Enable users to change VF/PF representors carrier stateParav Pandit1-0/+24
Currently PF and VF representor netdevice carrier is always controlled by controlling the representor netdevice device state as up/down. Representor netdevice state change undergoes one or more txq/rxq destroy/create commands to firmware, skb and its rx buffer allocation, health reporters creation and more. Due to this limitation users do not have the ability to just change the carrier of the non uplink representors without modifying the device state. In one use case when the eswitch physical port carrier is down/up, user needs to update the VF link state to same as physical port carrier. Example of updating VF representor carrier state: $ ip link set enp0s8f0npf0vf0 carrier off $ ip link set enp0s8f0npf0vf0 carrier on This enhancement results into VF link state change which is represented by the VF representor netdevice carrier. This enables users to modify the representor carrier without modifying the representor netdevice state. A simple test is run using [1] to calculate the time difference between updating carrier vs updating device state (to update just the carrier) with one VF to simulate 255 VFs. Time taken to update the carrier using device up/down: $ time ./calculate.sh dev enp0s8f0npf0vf0 real 0m30.913s user 0m0.200s sys 0m11.168s Time taken to update just the carrier using carrier iproute2 command: $ time ./calculate.sh carrier enp0s8f0npf0vf0 real 0m2.142s user 0m0.160s sys 0m2.021s Test shows that its better to use carrier on/off user interface to notify link up/down event to VF compare to device up/down interface, because carrier user interface delivers the same event 15 times faster.

2020-08-03Merge branch 'bpf-libbpf-btf-parsing'Daniel Borkmann6-148/+89
Andrii Nakryiko says: ==================== It's pretty common for applications to want to parse raw (binary) BTF data from file, as opposed to parsing it from ELF sections. It's also pretty common for tools to not care whether given file is ELF or raw BTF format. This patch series exposes internal raw BTF parsing API and adds generic variant of BTF parsing, which will efficiently determine the format of a given fail and will parse BTF appropriately. Patches #2 and #3 removes re-implementations of such APIs from bpftool and resolve_btfids tools. ==================== Signed-off-by: Daniel Borkmann <[email protected]>

2020-08-03tools, build: Propagate build failures from tools/build/Makefile.buildAndrii Nakryiko1-1/+2
The '&&' command seems to have a bad effect when $(cmd_$(1)) exits with non-zero effect: the command failure is masked (despite `set -e`) and all but the first command of $(dep-cmd) is executed (successfully, as they are mostly printfs), thus overall returning 0 in the end. This means in practice that despite compilation errors, tools's build Makefile will return success. We see this very reliably with libbpf's Makefile, which doesn't get compilation error propagated properly. This in turns causes issues with selftests build, as well as bpftool and other projects that rely on building libbpf. The fix is simple: don't use &&. Given `set -e`, we don't need to chain commands with &&. The shell will exit on first failure, giving desired behavior and propagating error properly.

2020-08-03mac80211: Do not report beacon loss if beacon filtering enabledLoic Poulain1-0/+3
mac80211.h says: Beacon filter support is advertised with the IEEE80211_VIF_BEACON_FILTER interface capability. The driver needs to enable beacon filter support whenever power save is enabled, that is IEEE80211_CONF_PS is set. When power save is enabled, the stack will not check for beacon loss and the driver needs to notify about loss of beacons with ieee80211_beacon_loss(). Some controllers may want to dynamically enable the beacon filter capabilities on power save entry (CONF_PS) and disable it on exit. This is the case for the wcn36xx driver which only supports beacon filtering in PS mode (no CONNECTION_MONITOR support). When the mac80211 beacon monitor timer expires, the beacon filter flag must be checked again in case it as been changed in between (e.g. vif moved to PS mode).

The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'ipw2100_msg_allocate()' (ipw2100.c), GFP_KERNEL can be used because it is called from the probe function. The call chain is: ipw2100_pci_init_one (the probe function) --> ipw2100_queues_allocate --> ipw2100_msg_allocate Moreover, 'ipw2100_msg_allocate()' already uses GFP_KERNEL for some other memory allocations.

When memory is allocated in 'bd_queue_allocate()' (ipw2100.c), GFP_KERNEL can be used because it is called from the probe function.

2020-08-02rt2x00: pci: use generic power managementVaibhav Gupta10-46/+19
Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. The callbacks make use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device() and pci_set_power_state() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use dev_get_drvdata() to get drv data. The .suspend() callback is invoking rt2x00lib_suspend() which needs to be modified as generic rt2x00pci_suspend() has no pm_message_t type argument, passed to it, which is required by it according to its declaration. Although this variable remained unused in the function body. Hence, remove it from the function definition & declaration. rt2x00lib_suspend() is also invoked by rt2x00usb_suspend() and rt2x00soc_suspend(). Thus, modify the functional call accordingly in their function body. Earlier, .suspend() & .resume() were exported and were used by the following drivers: - drivers/net/wireless/ralink/rt2x00/rt2400pci.c - drivers/net/wireless/ralink/rt2x00/rt2500pci.c - drivers/net/wireless/ralink/rt2x00/rt2800pci.c - drivers/net/wireless/ralink/rt2x00/rt61pci.c Now, we only need to bind "struct dev_pm_ops" variable to "struct pci_driver". Thus, make the callbacks static. Declare an "extern const struct dev_pm_ops" variable and bind PM callbacks to it. Now, export the variable instead and use it in respective drivers.

Without this patch, RTL8821CE will not have coex support, and will crash the system because of the NULL pointers for the coex functions. While RTL8822C series are WiFi + BT combo chips, it needs the co-existence mechanism for the device to work on both WiFi and BT without interfering each other. And the coex support has already been added before, most of the mechanisms are implemented. The driver should just add corresponding functions to operate on different types of chips and its coex parameters.

2020-08-02rtw88: coex: only skip coex triggered by BT infoYan-Hsuan Chuang1-1/+2
The coex mechanism used to skip upon the freeze flag is raised. That will cause the coex mechanism being skipped unexpectedly. Coex only wanted to keep the TDMA table from being changed by BT side. So, check the freeze and reason, if the coex reason is coming from BT info, skip it, to make sure the coex triggered by Wifi itself can work. This is required for the AP mode, while the control flow is different with STA mode. When starting an AP mode, the AP mode needs to start working immedaitely after leaving IPS, and the freeze flag could be raised. If the coex info is skipped, then the AP mode will not set the antenna owner, leads to TX stuck.

2020-08-02rtw88: fix short GI capability based on current bandwidthTsang-Shian Lin1-5/+6
Fix the transmission is not sent with short GI under some conditions even if the receiver supports short GI. If VHT capability IE exists in the beacon, the original code uses the short GI for 80M field as driver's short GI setting for transmission, even the current bandwidth is not 80MHz. Short GI supported fields for 20M/40M are informed in HT capability information element, and short GI supported field for 80M is informed in VHT capability information element. These three fields may be set to different values. Driver needs to record each short GI support field for each bandwidth, and send correct info depends on current bandwidth to the WiFi firmware.

2020-08-02prism54: islpci_hotplug: use generic power managementVaibhav Gupta1-23/+11
Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions as through the generic framework, PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.
